Abstract
A pneumatically striking hand-held power tool is controlled by the following steps. An acceleration (a) along a striking axis () of the hand-held power tool () is detected. A driving power is reduced if the detected acceleration (a) is greater than a threshold value (A), the threshold value (A) being selected to be greater than maximum acceleration values (a, a) that occur on a workpiece during the striking operation of the hand-held power tool ().
